Wipe your device to delete your data

Before you wipe your BlackBerry device, consider backing up your data on a computer. A security
wipe is designed to permanently delete your data so it can't be recovered. This
includes email accounts, downloaded apps, media files, documents, browser bookmarks,
and settings.

On the home screen, swipe down from the top of the
screen.

Tap Settings > Security and Privacy > Security
Wipe.

Type blackberry.

Tap Delete Data.

When the security wipe is complete, your device is turned off automatically. To turn
on your device, press the Power/Lock key on the top of
your device.

Tip: If you are planning to give away or recycle your device,
remember to also remove your SIM card and media card.

Delete your work space

If you no longer want to associate your device with your organization's
network, you can remove only your work space. The apps and files stored in your
personal space are left intact.

CAUTION:

Deleting the work space will permanently erase all of the
content and files stored within it, such as work files, messages, pictures, and
videos. To add a work account back to your device, you will need to contact your
adminstrator.
